LOUIS o. JANN, or BUFFALO, new YORK.

WATER-TRAP.

To all whom it may concern: Be it known that I, LOUIS C. JANN,-c1t1- zen of the United States, residing at Buffalo,

in the county of Erie and State-of New York, have invented certain new and useful Improvements in Water-Traps, of which the following is a specification.

My invention relates to water traps and more particularly to that class of traps which are used in connection with slnks and the like. r

The primary bject of my invention is to provide a trap which will be snnple in construction, cheap to manufacture, and one which is quickly and easily cleaned. I

A further object of my invention is to provide an improved cover for a trap of the character above described which will permit of the disposition of thetrap completely beneath the floor so as not to present an unsightly ppearance, which is the case in the present devices.

Another advantage of my invention is that the space taken up by the same is much less than the usual devices owing to the peculiar form of cover Provided.

With the above and other objects in View my invention resides preferably in the construction, combination, and arrangement of parts as hereinafter set forth in the specification and illustrated in the accompanying drawing, in which Figure 1 is a perspective view of my improved trap showing the same in position relative to the floorof a dwelling.

Fig. 2 is a vertical sectional view of the same.

Fig. 3 is a transverse section the supplemental cover.

Similar reference characters indicate simial view of 'lar parts throughout the various views of the drawings.

Referring more particularly to the drawings in which the preferred embodiment of my invention is illustrated the numeral 1 designates the water trap, preferably cylindrical in configuration and having inlet and outlet apertures 2 and 3, respectively, to which are secured inlet and outlet water conduits 4 and 5, respectively, the inlet conduit 4 leading from the sink or other fixture and passing through the floor 6 as shown at 7 in Fig. 1.

My improved cover comprises amain portion 8 having n externally threaded annular flange 9 formed on the under face Specification of Letters Patent.

Application filed June 8, 1915. Serial No. 32,955. i

by to close the same. A suitable water-tight washer 11 is carried by the cover 8 and serves to afford a non-leaking joint. As shown to advantage in Fig. 1, the trap body 1 is disposed beneath the floor 6, and in order to gain access to the trap and remove the cover 8 an aperture 12 of a slightly greater diameter than the diameter of the cover 8 is provided in the floor 6. In order to close the aperture 12 and also facilitate removal of the cover 8 I provide a vertical pillar or standard 13 carried by and preferably formed integral with the cover 8. The upper end of'the pillar 13 supports a supplemental cover 14 carried by and preferably formed integral therewith, which cover 14 is of such diameter as will close the aperture 12 in the manner shown. In order to facilitate removal of the covers 8 and 14 I provide a handle member carried by the supplemental cover 14 which comprises a bar, the intermediate portion 15 of which is adapted to seat in a. transverse recess or groove 16 in the upper face of the cover 14, the terminal portions of the bar 15 be ng downwardly bent as indicated at 17 for apertures 18 formed in the supplemental cover 14 approximately at the terminals of the groove 16. Theextremities of the portions 17 are outwardly bent as indicated at 19 to afford stop portions, and it will-be noted that when the handle 15 is gripped and an upward pull directed thereon, the portions 19 will engage the cover 14 and facilitate rotation of the same to draw the cover 8 carried by said cover 14 from the closed position. Normally the handle 15 remains in the position shown to advantage in Fig. 3 lying flush with the upper face of the cover 14.

From the above description taken in condrawing, it is thought that a clear and comprehensive understanding of the construction, use and advantages of my invention may be gathered. I desire to lay particular stress upon the peculiar manner in which the two covers 8 and 14 are connected by the pillar 13, as well as the manner in which the cover 14 serves to close the aperture 12 as shown. It will thus be seen that when the cover 8 is in closed position, nothing is visible above the floor and that the space heretofore taken.

up by the body 1 of the trap may be utilized for other purposes and the space between the floors and ceilings in dwellings can be placed to a good use, which has heretofore not been the case. Simplicity of my device is one of its principal and greatest advantages, but it will be understood that in practice certain changes within the scope of the invention as claimed may be made.

While I have shown and described my in vention as possessing a peculiar form and construction, it is desired that it be understood that I may make such changes in the details thereof that do not depart from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

In a water trap of the class described, the combination of a receptacle having an open upper end, said receptacle being internally threaded adjacent the open end, said receptacle being adapted to be positioned beneath a floor through an opening formed therein, a cover having an annular extending threaded flange, said flange being screwed into engagement with said receptacle, an integral pillar projecting upwardly from said cover,

a supplemental cover formed integral upon the upper end of said pillar, said last mentioned cover beingof greater dimensions than the first mentioned cover, whereby said supplemental cover may fit upon a floor for closing the opening therein, the integral formation of said covers upon said. pillar posie tively holding said supplemental cover against accidental movement when said first mentioned cover is; carried upon the receptacle, said supplemental eover being adapted to be rotated to rotate said first mentioned cover and flange for unscrewing the flange from engagement with said receptacle, and the formation of the supplemental cover upon the pillar causing the supplemental cover to be elevated as the flange is unscrewed froin engagement with said receptacle, thus causing the supplemental cover to be in a position to be easily gripped when desired and at all timesbeing in position to actuate the movement of the pillar;

In testimony whereof I alibi my signature in presence of two Witnesses,

LOUIS C. JANN. Witnesses Louisa T. JANN, Mrs. L. C. JANE.
